The pieces that I had, were "re-productions" in the same spirit, but they were not presented as Martens works. I attached a card with the master glassmaker name and the year of production to avoid possible confusions with the old original ones. The point is that I immediately received several request from antique dealers and traders who wanted reproductions copied from books. Due to I have seen so many pieces produced today sold as antique glass, I would not feel confident to buy glassworks too easy to be reproduced.
Sincerely
